When choosing the lifting pliers, the type of lifting pliers to be used should first be determined according to the characteristics of the lifting object. When hoisting, it is necessary to consider the selection of sling equipment suitable for the operation requirements, and the selected sling equipment should be adapted to the shape characteristics and specific requirements of the suspended object, and must not be used at risk if the conditions of use are not available.

　　When choosing the specifications of the lifting pliers, it is necessary to consider the size, weight, shape of the object to be lifted, as well as the lifting method to be used and other factors affecting the use of the sling, for the working force requirements given by the sling, it is necessary to choose both sufficient capacity, and can meet the use of the right length of the sling.

　　If multiple slings are used at the same time, the adaptability of the lifting tongs must be taken into account; The influence of the working temperature environment on the load load should be taken into account when choosing the lifting pliers. Careful consideration must be given to matching the end of the sling to the auxiliary accessories and lifting equipment.

　　Lifting tongs are often faced with ambient temperature when they are used, and the impact of ambient temperature on the use of lifting tongs is also great. In general, forging and casting hoist products can be used in general operating conditions with temperatures as low as -40°F, at which temperature increases at a steady rate. Avoid shock load; A thorough visual inspection should be carried out before each lifting; Repair nicks, gouges or cracks; Do not use lifting pliers fittings that have been welded or modified since the factory.

　　The high temperature environment that the lifting pliers can be used in is 400°F, high temperature may have an adverse effect on the rigging products containing non-metallic materials, lubricants and plastics, and the high temperature should not normally exceed 200°F; The surface finish of galvanized, plated or sprayed lifting gear fittings may be partially or completely damaged.

　　Exposure to high temperature for a long time can lead to serious lifting tongs surface shedding and significant performance degradation. Repeated heating and cooling to room temperature may result in tempering embrittlement of the lifting pliers.
